  • Publication number: 20160188120
    Abstract: An architecture is described that can utilize photo-sensors embedded in a substantially transparent layer of a UI display for tracking objects that approach or hover over the UI display. The photo-sensors can be configured to detect light of certain wavelengths (e.g., visible light, infrared light) that are propagated toward the UI display, while ignoring light emanating from the UI display when displaying content. Accordingly, by examining various characteristics of the incoming light such as intensity, the architecture can identify a location of a shadow incident upon the display caused by an approaching or hovering selector object blocking portions of incoming light. Additionally or alternatively, the architecture can identify a location of higher intensity for light emanating from the selector object.

  • Patent number: 9351026
    Abstract: Aspects of the subject disclosure may include, for example, identifying a request to record video content at a multimedia storage device, wherein the video content corresponds to a program having a scheduled broadcast time that occurs during a peak viewing period. Data is obtained to prevent viewing of the video content prior to the broadcast time. The video content, responsive to the identifying of the request, is sent selectively to the multimedia storage device during a non-peak viewing period prior to the peak viewing period. The video content includes the data to prevent the multimedia storage device from sending the video content to another device prior to the time when the program is scheduled to be broadcast. Other embodiments are disclosed.

  • Publication number: 20160087903
    Abstract: Systems and methods to select peered border elements for a communication session based on Quality-of-Service (QoS) are disclosed. An example method includes selecting a peered border element to handle a communication session based on a list of peered border elements (PBEs) and a composite QoS parameter of the communication session, the list of PBEs being prioritized based on respective statuses of PBEs in the list, the first composite QoS parameter being based on weighted QoS parameters of the communication session including a grade of service (GoS) parameter of the communication session and a preferred mode of communication for a VoIP device of a called party in the communication session, the GoS parameter including an attempted performance range and an expected performance range of the communication session; and controlling a second server to generate a QoS authorization token to reserve network resources associated with the selected PBE.

  • Patent number: 9294628
    Abstract: A method and apparatus for processing network origination calls in a hybrid network. A system that incorporates teachings of the present disclosure may include, for example, a network management system (NMS) having a detection module to detect at a first terminal a network origination call directed to a second terminal, a search module to search a terminal type for each of the first and second terminals according to information supplied in the network origination call, and an enablement module to enable at least one media gateway to provide communication services to each of the first and second terminals identified as a circuit-switched terminal by its corresponding terminal type. Additional embodiments are disclosed.

  • Patent number: 9294591
    Abstract: A method that incorporates teachings of the subject disclosure may include, for example, transmitting a first query to a domain naming server responsive to receiving a session initiation protocol message comprising a fully qualified domain name. The first query can include one of an internet protocol version 4 address query or an internet protocol version 6 address query associated with the fully qualified domain name. The method can include receiving at least one answer from the domain naming server. The at least one answer can include at least one of an internet protocol version 4 address having no errors, a second internet protocol version 6 address having no errors, or both. The method can also include transmitting a message to a communication device. The message can include information associated with the at least one answer.

  • Publication number: 20160065745
    Abstract: A method and an apparatus for completing a circuit switched service call in an Internet Protocol network are disclosed. For example, the method receives a session request and queries an tElephone NUmbering Mapping server for a called party, and determines if at least one Naming Authority Pointer resource record associated with the called party is received from the ENUM server. The method determines if a Session Initiation Protocol Universal Resource Identifier is returned, if the at least one NAPTR resource record associated with the called party is received, and processing the session request using the SIP URI, if the SIP URI is returned. The method determines if the processing of the session request using the SIP URI resulted in a successful call completion and processes the session request using a telephone URI, if the processing of the session request using the SIP URI resulted in an unsuccessful call completion.
